Part I. OverviewPrefaceThis Plan is the first in a series of documents that will address the Data Management and Communication(DMAC) requirements of the Integrated Ocean Observing System (IOOS), and other regional,national, and global observing systems. In the Preface, we provide some background informationto assist the reader in placing the DMAC Subsystem into its proper context as a componentof the larger IOOS. As such, the DMAC Subsystem will be developed, implemented, operated, andenhanced through the planning and governance structures described in the IOOS ImplementationPlan.IOOSThere is strong support in the U.S. Congress, the Executive Branch, and the U.S. Commission onOcean Policy (USCOP) for development of a sustained, integrated coastal and ocean observing systemthat will make better use of existing resources, new knowledge, and advances in technology toachieve the following seven related societal goals:• Improve weather forecasts and predictions of climate change;• Improve safety and efficiency of marine operations;• Provide more timely predictions of natural hazards and their impacts;• Improve national security;• Reduce public health risks;• Sustain, protect and restore healthy marine and estuarine ecosystems; and• Sustain, protect and restore marine resources.Congress directed the U.S. marine environmental communities to come together to plan, design,and implement this observing system. The National Oceanographic Partnership Program 1 (NOPP)established the Ocean.US Office through a Memorandum of Agreement (MOA) in 2000. Ocean.US is charged with coordinating the development of the U.S. Integrated Ocean Observing System,based on concepts developed by national and international experts over the past dozen years.Ocean.US is overseen by an Executive Committee (ExCom) composed of representatives fromthose NOPP agencies that signed the MOA.Ocean.US is preparing an IOOS Implementation Plan (www.Ocean.US), in cooperation with theparticipating NOPP agencies. The Plan is being developed in three parts: Part I—Structure andGovernance; Part II—The Initial IOOS: Building on Existing Assets; and Part III—Improving the1NOPP was established by Congress in 1997 (P.L. 104-201) to (1) ”promote the national goals of assuring national security, advancingeconomic development, protecting the quality of life, and strengthening the science and education through improved knowledgeof the ocean” and (2) “coordinate and strengthen oceanographic efforts to achieve these goals by ‘identifying and carrying outpartnerships among Federal; agencies, academia, industry, and other members of the oceanographic community in areas of data,resources, education, and communications.”11
